A starter that cannot be dynamically balanced is not a good motor!

Vibration failure of most rotating machinery

70% comes from the imbalance of the rotor system

Failure caused by rotor imbalance

About 60% of all mechanical failures

If the rotor system of the starter is unbalanced, it will cause

Large vibration when the starter is running

The motor is too loud

Accelerated damage to other parts due to severe vibration

Directly affect the performance life of the entire engine

So in the manufacturing process of the starter

The dynamic balance of the rotor system is crucial

So what does Yida do?

First look at Yida's rotor

Dynamic balance test

The dynamic balance test is to perform dynamic balance measurement and verification during the rotation of the rotor. Every rotor on the Yida production line must pass the test and meet the standards before it can be sent to the final assembly line.

Rotor dynamic balancing machine

High-precision dynamic balancing equipment, the dynamic balancing machine can measure the unbalanced rotor and perform dynamic balance correction on the rotor to control the vibration force within the standard range.

Balance slot correction

If the mass distribution at both ends of the rotor is not balanced, the rotor will vibrate strongly when rotating, which does not meet the dynamic balance standard. In order to achieve precise dynamic balance, it is necessary to remove some weight from the iron core laminations of the rotor shell (cutting grooves one by one, this process is called "milling balance grooves") to correct the mass distribution of the rotor.
